This is a library for interacting with the [certstream network](https://certstream.calidog.io/) to monitor an aggregated feed from a collection of [Certificate Transparency Logs](https://www.certificate-transparency.org/known-logs).

It is built to be compatible with both node.js and a standard browser with UMD.

# Installing

```
npm install --save certstream
```

Or if you're using this in the browser, just add `dist/certstream.min.js` to a `<script>` tag, and interact with it as normal!

# Usage

The CertStream API is extremely simple, all you have to do is register a callback and call `connect()`.

```javascript
const CertStreamClient = require('certstream');

let client = new CertStreamClient(function(message){
    console.log("Received -> ", message)
});

client.connect();
```

The `connect()` method takes a `url` argument for supplying a different certstream URL.

# Example data structure

The data structure coming from CertStream looks like this:

```

    "message_type": "certificate_update",
    "data": {
        "update_type": "X509LogEntry",
